Description

TECHNICAL FIELD The present invention relates to an actuator for an aerosol container, and more particularly to an actuator for an aerosol container and an aerosol product capable of applying a content to an application target and spreading the content on the application target with a simple operation.

In general, various types of actuators for aerosol containers have been proposed, such as antiperspirant deodorants, analgesic antiphlogistic agents, pest repellents, paints, household cleaners, etc. It is
For example, Patent Document 1 describes a push button (push button 2) capable of injecting a content from an injection port (injection portion 3), and a rotating device for spreading the content injected from the injection port (injection portion 3) on an application target. and a roller (roller 6), and the push button (push button 2) is configured to be connected to a stem provided on the upper part of the container opening of the aerosol container main body (aerosol container main body 1). actuators (attachments for aerosol canisters) are known.

The aerosol container actuator (aerosol container attachment) described in Patent Document 1 further has a cap-shaped mounting portion 4 ′ fitted to the upper portion of the aerosol container main body (aerosol container main body 1 ). ' has an extension 4-1 extending upwards of the container and a holding shaft (bearing 5) provided in the extension 4-1, and a rotating roller (roller 6) rotates around the holding shaft (bearing 5). It is freely fixed, and by pressing the push button (push button 2), the contents can be taken out from the aerosol container body (aerosol container body 1) and sprayed from the injection port (spray part 3) to the application target. A rotating roller (roller 6) can be used to spread the contents on the object to be coated.

However, the aerosol container actuator disclosed in Patent Document 1 still has room for improvement.
That is, in the aerosol container actuator known in Patent Document 1, the direction of the rotating roller is fixed. Therefore, there is a risk that it will be difficult to work in a narrow space and that uneven coating will occur.
In addition, since both ends of the rotating roller are supported, it is difficult to spread the content efficiently when spreading the content near a wall because the both ends of the rotating roller hit the wall. There was a fear that
In addition, when only the outer end of one of the two rollers rotatably attached to the same shaft is cantilevered (see FIG. 3 of Patent Document 1). Also, when spreading the content applied to the object to be coated, an unbalanced load is applied to the rotating roller, and there is a possibility that the shaft and the rotating roller may be deformed and distorted.

The present invention solves the above-mentioned problems, and has a simple structure, and is an aerosol that can easily spread the contents applied to the application object in any direction, has less uneven coating, and can easily spread the contents even near the wall. It is an object of the present invention to provide an actuator for a container.

The aerosol container actuator of the present invention has a push button connectable to the stem of the aerosol container and capable of ejecting contents from an ejection port, and a rotating roller for spreading the contents ejected from the ejection port on an application target. In the aerosol container actuator, the push button has a button body and a roller holding part provided with a nozzle part connected to the button body, and the roller holding part is aligned with the injection direction of the injection port. The rotating roller is rotatably held with a perpendicular holding shaft as a rotation axis, and the roller holding portion is configured to be rotatable relative to the button body with the injection direction of the injection port as a rotation axis. This solves the above problems.

According to the aerosol container actuator according to claim 1, the roller holding section rotatably holds the rotating roller about a holding shaft perpendicular to the ejection direction of the ejection port as a rotation axis, and the roller holding section rotatably holds the rotating roller. Since it is configured to be rotatable relative to the button body with the direction as a rotation axis, it is possible to change the direction in which the contents are spread by the rotating roller without changing the direction of the aerosol container body. The content applied on the object can be easily spread in various directions.
In addition, even when spreading the contents in a space with obstacles such as the walls, the rotating roller can be easily brought close to the walls and the contents can be spread reliably.
In addition, a plurality of rotating rollers can be arranged side by side so as to sandwich the nozzle section, and as a result, the load applied to the rotating roller can be distributed across the nozzle section, so that the nozzle section and the rotating roller do not receive an extreme unbalanced load. Therefore, deformation of the nozzle part and the rotating roller can be suppressed.

According to the configuration of claim 2, since the outermost peripheral portion of the rotating roller is positioned closer to the application target than the ejection port, the direction of ejecting the contents and the pressing direction of the rotating roller can be matched. , and the transition from the operation of injecting the contents to the operation of spreading the contents on the coating object can be performed quickly and without trouble.
According to the configuration of claim 3, a plurality of rotating rollers are provided, and at least one rotating roller is arranged on both sides of the nozzle portion, so that when spreading the content on the application target, the rotating roller The load applied when the is pressed against the application target can be dispersed, the deformation of the rotating roller and the nozzle part can be further suppressed, and the contents can be spread stably.
In addition, the rotating rollers can be arranged symmetrically with the nozzle portion interposed therebetween, thereby evenly distributing the load applied when the rotating rollers are pressed against the object to be coated, and further suppressing deformation of the rotating rollers and the nozzle portion. .

According to the fourth aspect of the invention, since the rotating roller is detachable from the roller holding portion, it can be replaced with a rotating roller having a desired material and structure according to the object to be coated.
In addition, since members other than the rotating rollers can be unified, it is possible to reduce the mold manufacturing cost and simplify inventory management.
According to the configuration of claim 5, at least a part of the nozzle part is configured to be detachable from the button body. When spreading the contents, the tip side of the nozzle part including the rotating roller is removed and used, so that only the rotating roller and the nozzle part enter the space to spread the contents.

The rotating roller 130 has a rubber surface and is formed in a cylindrical shape.

Next, a method of applying the content liquid to the object to be applied by the aerosol container actuator 100 will be described with reference to FIGS. 1 to 8. FIG.

First, the pressing surface 115 is pressed to push down the stem S via the button body 111 .
As a result, the contents in the aerosol container main body C are supplied from the stem S to the channel 117 .
When the stem S is held down, the content is further supplied from the aerosol container main body C, reaches the communication channel 125 from the flow channel 117, and is jetted from the injection port 122, thereby the content to be applied. applied.

Next, the content applied to the application target is spread over the application target using the rotating roller 130 .
At this time, the rotating roller 130 rotates around the holding shaft H as the center of rotation.
Further, since the sliding pipe 124 is slidably engaged with the sliding portion 123 , the rotating roller 130 can rotate together with the sliding pipe 124 .
